hosting asp.net out of IIS with MC++, strange exception.

[EP]

I am hosting asp.net outside of IIS, and my workerrequest derived class is written in MC++.

Of course adding a trust element to the config file doesn't change anything, and I have roughly the same implementation built in c# and it works fine.

Any Ideas?
